Technical Considerations

What is the maximum moisture of a raw material that the SCARABEY Line can process?

It depends on the raw material as the SCARABEY Line can effectively process the so-called shipping-dry wood and also wood with higher moisture content. According to current standards, to prevent rot spots on the wood its moisture during transportation should be less than 30%. Sawdust, shavings and any other woodworking waste have a moisture content of 10-15%, and if these are stored outdoors under shelter the moisture is 15-20%, which corresponds to the so-called air-dry wood. Fresh cut wood has a higher moisture, typically about 40-70%.

In the production of pellets from grass and haylage the SCARABEY Line can processing raw material with moisture content of up to 50%.

What should I do if the moisture of my raw material is more than 30%?

Wet raw material should be dried to the recommended 30%. For example you could use flue gas drying, however this process is expensive and fire hazardous. A safer method is sorption drying in which wet raw material is mixed with a predetermined amount of dry material and the average moisture content is thus reduced to the desired level.

How does the SCARABEY Line reduce the moisture content of a raw material from 30% to 12-16% required for pelletizing?

The SCARABEY Line includes a unique S.A.M.P.O. 2012 mill heater. The mill uses atmospheric air as a heat-transfer medium applying the method of vortex flow thermal separation similar to the well-known Rank-Hilsch effect. Moisture is additionally removed due to centrifugal force (for example, this drying method is used in washing machines with a spin function).

My raw material is very dry, will the SCARABEY Line be able to pelletize it?

The SCARABEY Line is equipped with a dosing pump that supplies water to S.A.M.P.O. 2012 milling and heating unit, when required. Water enters the mill chamber, transforms to a finely dispersed aerosol and uniformly moistens the raw material.

Does the SCARABEY Line have any in-built moisture indicator?

How can you check that the raw material moisture content at the outlet of the mill heater is optimal for pelletizing?

To produce high quality pellets, the SCARABEY Line does not require any accurate measuring of moisture of powder that goes from the mill heater to the pelletizer. Moisture can be easily monitored by appearance of the pellets. If the pellets are short, with lots of dust, water supply should be increased. If the resulting pellets are long but crumbly (like corn curls), the moisture content of the raw material is too high, and water supply should be reduced.

What is the maximum size of the raw material that can be processed by the SCARABEY Line?

The maximum feed size of particles should not exceed 30 mm.

My feed size is greater than 30 mm. What should I do?

The raw material should be reduced to the recommended size; hammer crushers would be typically used for this purpose. We produce hammer crushers specially designed for preparation of feed materials for the SCARABEY Line.

The SCARABEY Line can pelletize grass and haylage with moisture of 50% or less.

What is the type of pelletizer used in the SCARABEY Line?

The SCARABEY Line features an in-built original pelletizer with a flat die boasting high reliability and performance. The quality of pelletizers with flat dies is confirmed by such a well-known manufacturer as Amandus Kahl.

What is the service life of the rollers and pellet mill die?

The service life depends on the properties of the raw materials processed and amount of mineral impurities.

With wood, the service life of the rolls is typically 600 t. The service life of the flat die is up to 800 t.

What is the service life of the mill heater replaceable parts?

The mill chamber features a rotating rotor with replaceable blades. With wood, the service life of the blades is about 100-300 t, that of the replaceable ring forming the pulse chambers of the mill heater is 400-500 tons of wood waste.

Do the pellets resulting from the SCARABEY Line conform to European standards?

Density, dimensions and moisture content of the pellets produced with the SCARABEY Line are in full compliance with EN plus - A1 standards (DIN plus, ÖNORM M 7135, SS 18 71 20, as well as other European standards). Any other parameters (such as ash content, harmful substances content) depend on the quality of the feed materials. To produce high-quality pellets we recommend the wood with minimum amount of bark and mineral deposits.

What type of a die should I install in the SCARABEY Line?

For wood pelletizing, we recommend dies with thicknesses between 25 and 35 mm and openings of 6-8 mm. For pelletizing of wetter materials, such as grass, brewer's grains, grain stillage, we recommend installing dies with a thickness of 40-60 mm.

I’ve checked your website and it seems you haven’t dealt with my raw material. How can I find out if the SCARABEY Line will be effective for my type of raw material?

We are always happy to have an opportunity to test something new so we invite anyone with their samples of raw materials to our test site in Russia for a pelletization demo. If you can not provide your own raw material, we offer you to come to us and we will try to find a material similar to yours and bring it to our test site. One trial pelletization is absolutely free.

Is the SCARABEY Line certified in accordance with the European Union directives?

The SCARABEY Line is CE certified and meets all the requirements of the EU directives.

What is the SCARABEY Line power consumption?

Power consumption of the line is typically about 45 kWh.

What is the capacity of the SCARABEY Line?

The throughput capability depends on the type of raw material. With wood, it is typically 350-400 kg/h. With some materials, such as spent grains, sunflower husks, fallen leaves, the throughput rate can be 500 kg/h or more.

How long can the SCARABEY Line work without stopping?

The SCARABEY Line can work 8 hours without stopping. Then you need to stop the line, lubricate the bearing units and continue. Such maintenance typically takes about 5-10 minutes. We can also equip the SCARABEY Line with an automatic lubrication system, and in this case the line would not have to be stopped.

What premises is required for the “Skarabey” line?

The “Skarabey” line takes about 16 m2. The line installation does not require the concrete casting of foundation. It is sufficient to erect the frame at the solid foundation, for example, a concrete bed. All electrical equipment mounted at the “Skarabey” line is designed for operation at negative temperatures. However, at operation of the mill-heater with moist materials the condensate can arise at inner walls of the units to cause the clogging of the equipment. This is why it is recommended to maintain the indoor temperature not lower than plus 5°C.
